• High-purity aluminum is soft and ductile and thus, it is unsuitable for most commercial and engineering applications which require greater strength and hardness. Alloying, modification, cooling rate as well as heat treatment can increase the strength and hardness of aluminium alloys. In this study, the effects of heat treatment and modification were investigated with eutectic base Al-Si alloy (also known as LM-6 alloy). Silicon is the main alloying element that imparts high fluidity and low shrinkage, which results in good castability and weldability. Silicon's low thermal expansion coefficient is exploited for pistons and the high hardness of the silicon particles improves its wear resistance property. Strontium has the effect of refining the microstructure in a similar manner as achieved by using sodium. The effects of full heat treatment of LM-6 type alloy produced in green sand mould were also evaluated. Mechanical properties of the alloy have improved with all these variables, have been elaborated in this paper.
